Publisher's Summary

A private detective finds passion, danger, and the love of a lifetime when he hunts down a lost earl in Victorian London.

On the trail of an aristocrat's secret son, enquiry agent Mark Braglewicz finds his quarry in a music hall, performing as a trapeze artist with his twin sister. Graceful, beautiful, elusive, and strong, Pen Starling is like nobody Mark's ever met - and everything he's ever wanted. But the long-haired acrobat has an earldom and a fortune to claim.

Pen doesn't want to live as any sort of man, least of all a nobleman. The thought of being wealthy, titled, and always in the public eye is horrifying. He likes his life now - his days on the trapeze, his nights with Mark. And he won't be pushed into taking a title that would destroy his soul.

But there's a killer stalking London's foggy streets, and more lives than just Pen's are at risk. Mark decides he must force the reluctant heir from music hall to manor house, to save Pen's neck. Betrayed by the one man he thought he could trust, Pen never wants to see his lover again. But when the killer comes after him, Pen must find a way to forgive - or he might not live long enough for Mark to make amends.

What a climax!

My FAVORITE of the series! What a range of characters we’ve seen in these books. The MCs in this one blew me away, especially since they appeared in a historical romance!

Pen is a gender fluid trapeze artist. Mark is a pansexual man of inquiry. Mark sees Pen and he’s mesmerized. Pen sees Mark and is dubious of his seemingly honest attraction to and acceptance of him. I LOVED these two together, delighted in how they navigated understanding each others’ sexuality and creating trust. Only to have it purposefully destroyed.

That’s right, stuff happens and it’s not all good. People get hurt. It’s not all perfect, love and roses forever (well, OK, until the HEA).

This is the finale of a mystery that began two books ago. I’m usually pretty adept at figuring out whodunit. But here, I didn’t have a clue. Not at all. Zero. This both delighted and frustrated me to no end. Well done there, K.J. Charles, well done!

Pen is the likely heir to an earldom. He doesn’t want it. At all. But people are dying because of him. What to do? Read it and find out.

And if you’re hankering for an audiobook, the performance for this one was incredible!

Series ends on a high note

The final installment of the Sins of the City gives interesting characters, a nice narration and resolution of the mystery in KJ Charles' inimitable style. There is instant attraction between trapeze artist Pen and private investigator Mark that shows how gender fluidity can be beautiful. Pen struggles with being misunderstood and opens up to Mark's compassionate understanding. However, an unwanted title forces Pen to play the gentleman and violence follows in his wake. The mystery begun in the first book has a satisfying conclusion. You also get to catch up with Clem, Rowley, Nathaniel and Justin from the first two books of the series which is fun. The whole series is narrated by Matthew Lloyd Davis who does a fine job in character voice and development. I am beyond thrilled KJ Charles is getting turned into audibles and hope more of her books get the attention they deserve.

Fitting Conclusion

I enjoyed listening to An Unsuitable Heir , Book 3 and the last in the Sin of the City series.

All the plotlines were nicely closed . Some of the resolutions were unexpected yet welcomed. It did fit with the narrative, the time period and the characters.
The reason why and the villain/villains of murders mystery were explained ; I was surprised by who/whom turned out to be.

Matthew Lloyd Davies narration was superb.

I Highly Recommend This!

What would it be like to be a stranger in your own skin? What defines us, hair or clothes or other people's ideas on "proper" dress and deportment? This story gives us a few ideas on that as well as a delicious mystery to mull over.

This story is sensitive and well written. Another Masterpiece from KJ Charles.

Suitably entertaining romantic mystery


There’s an earl’s contested heir and a pile of trouble to keep the heir missing. Because who wouldn’t want to be a fabulously wealthy earl? Sensitively written to explain who’s who & what everyone’s motivations are for finding or silencing the heir, it’s a fine tale of misfits trying to just be themselves. Which means they all have learned to view the world a little sideways, and thus are more interesting characters than in an average story about earls.

Somewhat unexpected (to me) this conclusion to the trilogy was neatly written to overlap the previous two books’ timelines without rehashing more than a moment or two. We see Clem, Roly, Lazarus & Nathaniel while Mark does his best to figure out what is going on. And falls in love.

Steam: Med-Low Some details on page but not a lot of dwell time. Mostly concerns how to be comfortable in a body that doesn’t fit in, in one way or another.

Narration: Same solid narration as previous installments. Emotional moments done empathetically, easy to follow along. Good quality.

goes past ordinary gender roles

KJ Charles' characters are do real. They go beyond hot guy falling into bed with another hot guy. I love her inclusion of characters with special needs, mix races, and gender fluidity!

Really interesting original characters completing trilology

Loved the two characters and performance by Mathew Lloyd Davis, a great conclusion to the trilogy. As usual my only complaint is I wish it was longer and I was sad when it was over.

KJ Charles has quite a talent

This is my third series of books I have read by KJ Charles. TBH, Sins of the Cities was my least favorite of those three, with A Charm of Magpies series being my fav (of KJ Charles and at the top of my list otherwise) and Society of Gentlemen series coming in second. I was never really attached to the characters of this Sins of the Cities series but still enjoyed the read/listen . KJ Charles has such a gift for creating characters that have opposing views/lifestyles with very compelling arguments for each of their POV's and working up situations that seem like there would be no comfortable way for them to survive much less reach their HEA, and yet they do and I am impressed by how all the tangles of story wind around to end up with me being happy with the outcome each time. I know this is an overall review of KJ Charles, but with this being my least fav of the three series I have read but still find the writing passionate, intelligent and clever I don't want to sound negative. In An Unsuitable Heir I found the characters interesting, esp. Penn of course.. and I liked Mark and how Mark saw Penn. The mystery was less interesting that the other two series to me and for the first time in a KJ Charles book I was able to predict how this story would play out. The narration by Matthew Lloyd Davies always brings these books to life. The varied characters voices , the passion and the rough edged moments, all done so well , he breathes life into these characters.

gender non-conforming main character!!!

I love this whole series but the Pen made this extra special! As a transgender woman, I love seeing trans, gender queer, non-binary, and gender fluid characters in romances.

last one

This is the conclusion of the series where the murder is finally revealed. I enjoyed this one the most of the 3. Greta and Pen had much to do with that.
